The following probably speaks to Sirius XM silliness more than anything else, but what are you gonna do? Sonos’ Multi-Room Music System is now fully compatible with the “new and improved” Sirius XM stream. The system had worked on the Sirius side of things just fine, but now it works on the XM side of things, too.
XM now works because Sirius XM updated its Web feed a few weeks ago, which, judging by comments here and there, meh, it would be charitable to call the new player “OK.” The iOS and Android Apps still seem to work OK, which is good enough for me since I rarely (read: never) use the actual Web player.
Baby steps for Sirius XM.
